 nostr:npub17wkkj73azdfr23hmgd07fn0h39xvy0w72garahk5p8hg8jv8dx5s09uzqr I can see a possible issue with this solution though: If the PWM MOSFET has a low-impedance driver and is doing very hard edges, when it switches from off to on, the channel MOSFET's gates will momentarily stay at their old voltage, since they are driven low through high-impedance resistors to the common node, while their sources dive low along with the common node. This leads to a momentary positive V_GS that could possibly turn them on for a bit.
